The spokeswoman said the file, which contained printouts and duplicates of documents most of which are available online, as well as in-house notes on legal questions, was last seen on Oct. 9 and noted as missing on Oct. 12.

Although the loss of the file is "annoying", it is not "highly problematic," the spokeswoman said.

She said the state chancellery had reported a criminal offence and had interviewed several employees to see whether they had noticed anything unusual, but this had not led to any concrete results.

Bild daily had reported previously that a "secret file" on VW had gone missing.
